What indicates the Protective Breathing Equipment (PBE) is present inside the hard-side bracket during preflight?

• A. PBE present inside bracket
• B. PBE missing from bracket
• C. Humidity indicator blue
• D. Seal intact

Answer: (A)

The main idea here is a direct visual check: you confirm the PBE is in its designated spot by seeing it inside the hard-side bracket. That clear, physical indication is the most reliable way to know it’s present and ready for use. The humidity indicator being blue only tells you about the pack’s humidity status, not whether the PBE is actually installed. An intact seal shows the packaging hasn’t been opened, but doesn’t prove the PBE is inside the bracket. So the presence of the PBE inside the bracket is the best, most straightforward indicator.
